What color should i paint my car?

It's all personal preference my friend, but I wouldn't do flat black but that's just an opinion. Flat black does look good in the right cirstances but you are spending a lot of elbow grease and time prepping the car and flat black will look unfinished. Also consider that flat color is well flat. Cannot wax it and cleaning will be hard to do as well. What do you think about a darker hue of red? Check out something along the lines of a darker red an example would be Ford's Redfire Metallic. One other thing to consider is interior color, pick something that will go with the interior unless you plan on changing it or don't really care about matching. One other suggestion if you are painting this yourself and don't have a lot of experience at painting auto parts stores like Autozone sell paint that is ready to spray strait out of the can. No need to add thinners etc. They sell this paint in red, blue, black, etc. Take care and good luck!!
